Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movable spoiler devices face interference issues with electrical components and wiring harnesses due to their movement, necessitating improved installation layout.
Innovation Solution
A movable spoiler device design featuring a fixed plate, movable plate, link mechanism, electrical component, and wire harness, where the wire harness is fixed at one end to the movable plate and bent at the other end to the fixed plate, allowing it to unfold without interfering with the movement of the spoiler device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical components and wiring harnesses are installed near the movable spoiler device, then the aerodynamic performance can be adjusted by moving the spoiler, but the wiring harness interferes with the movement of the movable spoiler device
Solution Approach 1:
The wire harness is designed to be flexible and dynamically adjustable, allowing it to change its configuration as the movable plate moves between storing and unfolding positions. This dynamic adaptation prevents interference with the spoiler's movement while maintaining electrical connectivity.
Solution Approach 2:
The wire harness is routed through a third dimension by passing it through the link mechanism structure rather than laying it flat on the surface. This spatial reconfiguration allows the harness to accommodate the movement of the movable plate without creating interference in the two-dimensional plane of motion.
2Reliability
If the wire harness is fixed rigidly to the vehicle body, then the electrical connection is stable, but it interferes with the movement of the movable plate
Solution Approach 1:
The wire harness transitions from a rigid fixed connection to a dynamic flexible connection that can adapt its position. By routing the harness through the link mechanism and allowing it to bend and unfold, the system maintains reliable electrical connection while accommodating the full range of motion of the movable plate.
Solution Approach 2:
The link mechanism serves as an intermediary structure that the wire harness passes through. This intermediary arrangement allows the harness to be indirectly connected to both the fixed plate and the movable plate, enabling movement while maintaining electrical connectivity without direct rigid attachment.
3Ease of operation
If the wire harness is made flexible to allow movement, then the spoiler can move freely, but the electrical connection may become loose or disconnected
Solution Approach 1:
The wire harness is pre-routed through the link mechanism structure and secured at appropriate positions before the movable plate begins its movement. This preliminary arrangement ensures that as the plate moves, the harness follows a predetermined path that maintains tension and connection integrity without requiring real-time adjustment.
Solution Approach 2:
The link mechanism acts as an intermediary that guides and supports the wire harness during movement. By passing the harness through this intermediate structure, the system ensures the electrical connection remains stable and organized while allowing the movable plate to move freely within its range.

AI summary
A movable spoiler device includes a fixed plate fixed on a vehicle body of a vehicle; a movable plate arranged to be movable between a storing position and an unfolding position closer to the rear than the storing position; a link mechanism provided with one end pivotally supported on the fixed plate and the other end pivotally supported on the movable plate; an electrical component arranged in the vicinity of the movable plate; and a wire harness configured for connecting the electrical component to a battery arranged on the vehicle body. A first portion of the wire harness is fixed at the other end of the link mechanism corresponding to the movable plate, and a second portion of the wire harness is bent on the one end of the link mechanism corresponding to the fixed plate.
